Application filed June 177 1914.

To all f whom it muy concern .lle it known that I, WILLIAM VVA'rrin, acitizen of the United States, residing at lirorcester., in the county of)Vorcester and machine and particularly to a machine for I0\ assemblinga plurality of cylindrical articles in axial alinement.v J

The machine is designed especially for assembling the spacing tubes androlls used in the pattern chains which control the operation of loomharness mechanisms. In preparing these mechanisms for shipment it isnecessary to assemble large numbers of the rolls and tubes upon smallrods, which are thereafter placed in position in the pat# tern chains.This assembling operation has been ordinarily performed by hand and isav tiresome and comparatively expensive operation.

The object of provide a machine which will automatically arrange thesearticles in axial alinement so that they may be quickly and easilyplaced upon the rods above mentioned. To the accomplishment of thisobject my invention l*contemplates the provision of a hopper and avertically movable lifting plunger reciprocating therein, the plungerhaving its upper face so formed that it will carry .With it in itsupward movement a number of the cylin-` drical articles.

My invention also comprises means for removing transversely from theplunger larticles improperly positioned thereon and means for removinglongitudinally from the plunger the articles which are prtopei'lypositional in axial alinement. f

Provision is also made for preventing displacement of the cylindricalarticles during their longitudinal removal from' the lifting plunger.

Uther features of my invention will be hereinafter described and moreparticularly pointed out-in the appended claims.

A preferred form of the invention is shown in the drawings in Which-4FigureV 1 is a side elevation of themaohineFigxQ is a vien similar toFig. 1 but showing the parts in va different position; Fig. 3 isanelevation of the side of the mamy present ingieiition is toAssniuBnING-Mnoniivn.

chine opposite to that shown in Figs. 1 and 2: Figs. 11 and 5 aresectional views taken along the line 4 5 in Fig. 1 and showing' thelifting plunger and its operating mechanisin in two different positions,and Fig. 6 is a detail sectional View on the line 61-6 in ing. i.v

As shown in the drawings, I have pro-v vided a'hopper 10 which isopenfat its upper side and which may be provided, as shoivn in Figs. land 5', with a bottom Which slopes inwardly from each side toitslongitudinal center line. This sloping bottom may be an integral part ofthe hopper itself or may be formed by inserting separate wooden blocksl11 as a false bottom in the hopper. A lifting plunger 12 is mounted toslide i vertically through a slot ,extending longitudinally of thehopper. The plunger 12 has va 4depending projection 13 connected by anadjustable link 14: to an arm 15a (Figs. 1 and 2) of the bell cranklever 15. The arm 15b of the lever 15 carries a cam roll 16 Whichengages a cam 17. The cam 17 is Xed upon a shaft 18 mounted in suitablebearings and having at its opposite end a gear 19 (Fic- 3) meshing witha pinion 20 upon a shaft` 21 carrying a pulley 22 connected by a belt 23to any suitable source of power.

The upper surface of the lifting plunger 12 is recessed at 2i (Figs. 1and 5) and'when the plunger is moved' 'fr'pm the position shown in F ig.f1

to that shown in4 l? ig. 5 a number of the cylindrical articles whichhave fallen into the recess 24 Will be raised with the plunger to itsupper position.

` )Vlien the machine is used for assembling certain kinds of articles aset of separators 25 is used.4 These separators are mounted g upon avertically sliding rod 26 (Figs. 4 and 5) and normally rest adjacent theupper surface of the plunger 12`(Fig. Ll). The sliding rod Q6 has aprojection 27 at its lower end to which is pivoted a lever 28 supportedupon a shifting fulcrum 29 formedV inthe upper end of a link 30 Which isconnected to move vertically with the plunger 1Q. A stop 31 (Fig. 5) isadjustably secured to the frame of the machine by a bolt 32,

said stop being secured, in adjusted position by a screw 33 and loclrnut34, the screw 33 contacting With a fixed portion of the frame. As theplunger 12 moves upward the separators 25 move Awith the plunger untilthe outer end ofthe lever 28 contactsdwith the stop 31. The stopthereafter prevents further upward movement of the outervend of positionthe separators will be found in the position shown in Fig. 5. Thefunction of the separator is. to position the rolls trans- .versely ofthe recess and in axial alinement thereon as.- shown in Fig. 1. When the-machine is used for assembling tubes in lwhich the length equals orexceeds the diameter, the separators are not necessary.

After each upward movement of the plun ger a certain number of the rollswill be found in the position indicated in Fig. 1 While the other rollswill be caught in various positions upon the plunger and separators.These rollsl Will Iusually project higher than .the vrolls properlypositioned and 'I provide a brush 35 to remove the improperly positionedrolls transversely from the plunger and separators. The brush is mountedinbearings 36 on the frame of the machine and is provided at one end'With a beveled pinion 37,(Figs. 1 and 2)meshing with a beveled gear 38upon a short g transverse shaft 39 mounted in a fixed bracket 40 (Fig.3). At itsrear end the shaft 39 carries a crank arm 41 connectedv by arod '42 to a crank pin 43 mounted vto rotate with Ha pinion 44 meshingwith the l driving lpinion 20 upon the shaft 21. The

reciprocating stroke of the rod 42 is not su'iiicient in extent to givea complete revoluL tion to the shaft 39 but it communicates a to-and-fromotion thereto,.thus giving thel brush 35 alternating 'A partialrotations in opppsite directions. These movements of the'br'ush 35 areeffective to dislodge any rolls which have been raised by the plunger 12and are improperly positioned thereon.

I will now describe the devices for removing the properly positionedrolls longitudinally from ther plunger While it is in its raisedposition. AA horizontally extending guide 45" (Figs. land 2)v is securedto the frame of the machine and provides meansv for longitudinallyguiding a reciprocating plunger 46. This plunger has adepending.

` pivoted to the frame at75 and having a cam roll 76 coperating With acam 7 7 mounted, upon the shaft. 18. A rod 78 is connected to. the lever74 upon the same pivot as the cam member: 47 secured thereto and isconnected by a link 48 to a lever 49 pivoted -to the frame lof themachine at 50. The lever 49 carries a stud 51 connected by an adjustablelilik 52 to an operating lever 53. The lever 53 vcarries a cam roll 54Which coperates Witha cam 55,

i by Which connections the levers '53 and 49,

are'reciprocated. The link 52 is connected tothe studv 51 by a yieldingor giveaway connection of peculiar ferm. vThis connection comprises alongitudinally slotted casting 56 hailing a projection 57 formed thereonand having an arm 58 pivoted thereto at 59.. The arm 58 is forceddownwardly by a spring 60 positioned between the arm 58 and theprojection 57, and thus engages the stud 51. Should the horizontalmovement of the plunger 46 be obstructed7 the stud 51 will raise the arm58 and thereafter slide vfreely along the slot in the casting 56 Withoutdamage to the apparatus. When the 'feeding plunger .t6/ moves to theright in Fig. 1, the separators 25 are in their raised position and therolls are moved 'longitudinally alongthe recess in the lifting plunger12 as shown in Fig. 2. As they pass longitudil nally from the liftingplunger they are rel? ceived in a grooved deliveryfarml secured to theside of the machine.

l llhen the machine is used with .rolls of the relative dimensions showninthe drawings, it has been -found desirable to prevent `theirdisplacement as they are moved axially,

and accordingly I have provided a rod 62 (Fig. 2) which moves with thefeeding -plunger 46 but at greater speed so that it isprojected from thelplunger as the plunger advances, thus extending through the vholes inthe center of the rolls and preventing their displaeement. This rod 62has'a depending arm 63 (Fig. 1) secured thereto at the rear end, Whichis pivotally connected by a link -64 to a bell crank 6'5 pivoted at 66to the depending member 47 secured `to the plunger 'a differentialmovement at greater 'speed than the plunger 46. The rod is thusprojected-in advance of the plunger and by extending Athrough the holesin the rolls prevents their lateraldisplacement. -I have also providedmeans for holding the rolls on the delivery arm lxbetween thekfeedingmove- I nents of the plunger 46. This means comprises a clamp 70 (Figs.1 and .2) mounted upon 'a bar 71 suitably guided for vertical movementin the bracket 72 which supports the delivery arm 61. The bar 7x isconnected by an adjustable link 73 to\a lever 74 '77. Theclampr'O isthus positively raised by the cam-77,5but is yieldingly forced down#ward by the spring 8O and also by its ovrn Weight. Thecam 77 is so timedthat the clamp 7 O will be raised during the feeding aslollowsk Asupply-of rolls nasales indicated in connection with the foregoingdescription but may be briefly summarized or tubes is placed in thehopper l and at each raising of the plunger l2 a certain number of theserolls will be positioned as shown in Figs. l and 5. Asithe plungerreaches its upper limit the separators 25, are moved above the tainedtherein, means Aplacement 'during transfer.

rolls and the` brush 35 remov'es the improperly positioned rollstransversely. i The clamp y l is raised and the feeding plungerl 46moves forward to transferA the properlypositioned rollszto the deliverylAt the same time, the rod 62 advances faster than4` the plunger 46 andis projected through the center ofthe rolls thus preventing theirdisfeeding plunger are prevents the displacement of the rolls heldvinthis Yposition the attendant passes a rod'ithrough the required numberof rolls and?. removes them from the delivery arm as theblam'p 70 is aain raised,

, When the mac ine is used for assembling cylindrical articles invihichfthe length :is greater are unnecessary and the reciprocating rod62 can also be omitted. The briishf will, of course, be positionedvertically to correspond with the diameter of'the articles beingassembled.

Having will be evident thus described my invention it that many changesand modifications can be made therein by one skilled in the art Withoutdeparting from the spirit and scope thereof as expressed in the claimsand I do not wish to be limited to the details herein described exceptas required by the claims, but .l
